Answer:
The correct option is;
D. 45%
Explanation:
From the Hardy- Weinberg law, we have;
p² + 2·p·q + q² = 1
p + q = 1
Where:
p = Dom inant allele frequency in the population
q = Recessive allele frequency in the population
p² = The percentage of individuals in the population that are hom ozygous dominant
q² = The percentage of individuals in the population that are homo zygous recessive
2×p×q = The percentage of hete rozyous individuals in the population
The number of individuals that express the recessive phenotype = 86
The number of individuals in the population = 200
The percentage of individuals that express the recessive phenotype, q² = 86/200 = 0.43
Therefore;
q = √0.43 = 0.656
p + q = 1
p = 1 - q = 1 - 0.656= 0.344
∴ The frequency of individuals that express the do minant phe notype, p = 0.344
The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%
Answer:
<h2>2. Peter's maternal grandfather has PKU.</h2>
Explanation:
- Such type of the genetic disorder in which two copies of a gene must be mutated at a time is called autosomal recessive disorder such as sickle cell anemia, phenylketonuria, and some other diseases.
- When a sing copy of a gene is mutated in a person then this disorder is not appeared and the person is called a carrier.
- So when a child is born by two carrier parents then there is a chance that a child will be affected if both the parents donate mutated genes.
- In the case of Peter, since peter does not show this defect this means his maternal grandfather was affected by this disorder.
Answer:
Processing and storing food.
Explanation:
The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.
The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.
The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.
Thus, Processing and storing food is correct.
